Synthesis of Superabsorbent Polymer Hydrogels with Rapid Swelling : Effect of Reaction Medium Dosage and Polyvinylpyrrolidone on Water Absorption Rate

A superabsorbent polymer (SAP) was synthesized by solution polymerization. The influence of synthesis technology was studied and optimized, and FTIR, SEM, and TGA were used to characterize the structure and morphology of the material. Under the optimal synthesis conditions, the water absorption of t...

520 |a A superabsorbent polymer (SAP) was synthesized by solution polymerization. The influence of synthesis technology was studied and optimized, and FTIR, SEM, and TGA were used to characterize the structure and morphology of the material. Under the optimal synthesis conditions, the water absorption of the material can achieve about 80% of the saturation value in the first 20 min, and the material absorbs distilled water up to 2013 g/g. The SAP also has remarkable water retention and reswelling capability. The excellent performance makes it have a promising application in agriculture. In addition, the results show that the dosage of the reaction medium is a major factor for performance. Under the condition of the optimum value of other factors, the influence of the dosage of the reaction medium on water absorption can reach about 1000 g in distilled water
